I saw this problem recently. With this kernel-doc: * Note: some important info * * Note: other important info kernel-doc uses the "section name" (preceding the ':', like "Note") as a hash key for storing the descriptive text ("blah important info"). It is (was) possible to have duplicate (colliding) section names, without any kind of warning or error. kernel-doc happily used the latter descriptive text for all instances of printing the <section-name> descriptive text and the former important info was lost. One way to "fix" this is to modify the kernel-doc comments, e.g.: * Note1: foo bar * * Note.2: blah zay For now, kernel-doc will signal an error when it sees colliding section names like this.

Annoying gcc warning: fs/fat/inode.c: In function 'fat_fill_super': fs/fat/inode.c:1222: warning: comparison is always false due to limited range of data type Change it to compare with 4K instead of PAGE_CACHE_SIZE, as suggested by OGAWA-san.

I received a complaint that some FAT formated medias (e.g. sd memory cards) trigger a "unknown partition table" message even though there is no partition table and they work correctly, while in general (when e.g. formated with mkdosfs or even Windows Vista) this message is not shown. Currently this seems only to happen when the medias get formatted with Windows XP (and possibly Win 2000). Then the boot indicator byte contains garbage (part of text message) and so do the other parts checked by msdos_paritition which then later triggers this message. References: novell bug #364365 Most fat formatted media without partition table contains zeros in the boot indication and the other tested bytes and so falls through the checks in msdos_partition, leading it to return with 1 (all is fine). But some (e.g. WinXP formatted) fat fomated medias don't use boot_ind and so the check fails and causes a "unkown partition table" warning eventhough there is none and everything would be fine. This additional check directly verifies if there is a fat formatted medium without a partition table. Signed-off-by:

The on-disk media specification field in FAT is only 8-bits, so testing for <=0xff is pointless, and can generate a "comparison is always true due to limited range of data type" warning. While we're there, convert FAT_VALID_MEDIA() into a C function - the present implementation is buggy: it generates either one or two references to its argument.

This patch fix the problem that the buffer allocated for convert of unicode to utf8 in fat/dir.c is too small. And cannot handle filename with 255 asian characters when mounted with utf8 options. Also it fix the filename length limitation checking in vfat/namei.c that the filename length should be checked against the number of converted unicode characters. Not the length before NLS/UTF8 converted. Signed-off-by:

On the systems, ftruncate() which expand size for FAT became the cause of OOM. The cont_expand_zero() filled all memory with dirty pages, and since disk is very slow, limit of page scanning was exceeded, then it triggered OOM. This adds balance_dirty_pages_ratelimited() to avoid filling memory with dirty pages. Signed-off-by:

Currently, free_clusters is not updated until it is trusted, because Windows doesn't update it correctly. But if user is using FAT driver of Linux, it updates free_clusters correctly. Instead, this updates it even if it's untrusted, so if free_clustes is correct, now keep correct value. Signed-off-by:

Normally utime(2) checks current process is owner of the file, or it has CAP_FOWNER capability. But FAT filesystem doesn't have uid/gid as on disk info, so normal check is too unflexible. With this option you can relax it. Signed-off-by:

Fix fat_setattr() on the case of showexec option. If user specified showexec option, inode->i_mode may not have S_IXUGO. This just use inode->i_mode to fix it. And with this patch, we don't allow chmod() on memory inode, it's just bad behaviour. IOW, we allow changing S_IWUGO only which can be stored to disk. Signed-off-by:

Quota files cannot have tails because quota_write and quota_read functions do not support them. So far when quota files did have tail, we just refused to turn quotas on it. Sadly this check has been wrong and so there are now plenty installations where quota files don't have NOTAIL flag set and so now after fixing the check, they suddently fail to turn quotas on. Since it's easy to unpack the tail from kernel, do this from reiserfs_quota_on() which solves the problem and is generally nicer to users anyway. Signed-off-by:

If the block allocator gets blocks out of system zone ext3 calls ext3_error. But if the file system is mounted with errors=continue retry block allocation. We need to mark the system zone blocks as in use to make sure retry don't pick them again System zone is the block range mapping block bitmap, inode bitmap and inode table.

There are several cases where the running transaction can get buffers added to its BJ_Metadata list which it never dirtied, which makes its t_nr_buffers counter end up larger than its t_outstanding_credits counter. This will cause issues when starting new transactions as while we are logging buffers we decrement t_outstanding_buffers, so when t_outstanding_buffers goes negative, we will report that we need less space in the journal than we actually need, so transactions will be started even though there may not be enough room for them. In the worst case scenario (which admittedly is almost impossible to reproduce) this will result in the journal running out of space. The fix is to only refile buffers from the committing transaction to the running transactions BJ_Modified list when b_modified is set on that journal, which is the only way to be sure if the running transaction has modified that buffer. This patch also fixes an accounting error in journal_forget, it is possible that we can call journal_forget on a buffer without having modified it, only gotten write access to it, so instead of freeing a credit, we only do so if the buffer was modified. The assert will help catch if this problem occurs. Without these two patches I could hit this assert within minutes of running postmark, with them this issue no longer arises. Thank you, Signed-off-by:

Currently at the start of a journal commit we loop through all of the buffers on the committing transaction and clear the b_modified flag (the flag that is set when a transaction modifies the buffer) under the j_list_lock. The problem is that everywhere else this flag is modified only under the jbd lock buffer flag, so it will race with a running transaction who could potentially set it, and have it unset by the committing transaction. This is also a big waste, you can have several thousands of buffers that you are clearing the modified flag on when you may not need to. This patch removes this code and instead clears the b_modified flag upon entering do_get_write_access/journal_get_create_access, so if that transaction does indeed use the buffer then it will be accounted for properly, and if it does not then we know we didn't use it. That will be important for the next patch in this series. Tested thoroughly by myself using postmark/iozone/bonnie++. Signed-off-by:
