Fix slab corruption caused by alloc_cpumask_var_node() overwriting the tail end of an off-stack cpumask. The function zeros out cpumask bits beyond the last possible cpu. The starting point for zeroing should be the beginning of the mask offset by a byte count derived from the number of possible cpus. The offset was calculated in bits instead of bytes. This resulted in overwriting the end of the cpumask. Signed-off-by:

Pass the original flags to rwlock arch-code, so that it can re-enable interrupts if implemented for that architecture. Initially, make __raw_read_lock_flags and __raw_write_lock_flags stubs which just do the same thing as non-flags variants. Signed-off-by:

SGI has observed that on large systems, interrupts are not serviced for a long period of time when waiting for a rwlock. The following patch series re-enables irqs while waiting for the lock, resembling the code which is already there for spinlocks. I only made the ia64 version, because the patch adds some overhead to the fast path. I assume there is currently no demand to have this for other architectures, because the systems are not so large. Of course, the possibility to implement raw_{read|write}_lock_flags for any architecture is still there. This patch: The new macro LOCK_CONTENDED_FLAGS expands to the correct implementation depending on the config options, so that IRQ's are re-enabled when possible, but they remain disabled if CONFIG_LOCKDEP is set.

Make reiserfs3 return f_fsid info for statfs(2). By Andreas' suggestion, this patch populates a persistent f_fsid between boots/mounts with help of on-disk uuid record. Randy Dunlap reported a compiling error from v2 patch like: fs/built-in.o: In function `reiserfs_statfs': super.c:(.text+0x7332b): undefined reference to `crc32_le' super.c:(.text+0x7333f): undefined reference to `crc32_le' Also he provided helpful solution to fix this error. The modification of v3 patch is based on Randy's suggestion, add 'select CRC32' in fs/reiserfs/Kconfig. Signed-off-by: -

Currently many file systems in Linux kernel do not return f_fsid in statfs info, the value is set as 0 in vfs layer. Anyway, in some conditions, f_fsid from statfs(2) is useful, especially being used as (f_fsid, ino) pair to uniquely identify a file. Basic idea of the patches is generating a unique fs ID by huge_encode_dev(sb->s_bdev->bd_dev) during file system mounting life time (no endian consistent issue). sb is a point of struct super_block of current mounted file system being accessed by statfs(2). This patch: Make adfs return f_fsid info for statfs(2), and do a little variable renaming in adfs_statfs(). Signed-off-by:

This patch adds preadv and pwritev system calls. These syscalls are a pretty straightforward combination of pread and readv (same for write). They are quite useful for doing vectored I/O in threaded applications. Using lseek+readv instead opens race windows you'll have to plug with locking. Other systems have such system calls too, for example NetBSD, check here: http://www.daemon-systems.org/man/preadv.2.html The application-visible interface provided by glibc should look like this to be compatible to the existing implementations in the *BSD family: ssize_t preadv(int d, const struct iovec *iov, int iovcnt, off_t offset); ssize_t pwritev(int d, const struct iovec *iov, int iovcnt, off_t offset); This prototype has one problem though: On 32bit archs is the (64bit) offset argument unaligned, which the syscall ABI of several archs doesn't allow to do. At least s390 needs a wrapper in glibc to handle this. As we'll need a wrappers in glibc anyway I've decided to push problem to glibc entriely and use a syscall prototype which works without arch-specific wrappers inside the kernel: The offset argument is explicitly splitted into two 32bit values. The patch sports the actual system call implementation and the windup in the x86 system call tables. Other archs follow as separate patches. Signed-off-by:
