Currently, project quota could be changed by fssetxattr ioctl, and existed permission check inode_owner_or_capable() is obviously not enough, just think that common users could change project id of file, that could make users to break project quota easily. This patch try to follow same regular of xfs project quota: "Project Quota ID state is only allowed to change from within the init namespace. Enforce that restriction only if we are trying to change the quota ID state. Everything else is allowed in user namespaces." Besides that, check and set project id'state should be an atomic operation, protect whole operation with inode lock. Signed-off-by:

Once umount is called, sync_filesystem() in generic_shutdown_super() will skip syncng dirty inodes due to sb_rdonly check, leaving dirty inodes there. To solve this issue, during umount, add remove SB_RDONLY flag in sb->s_flags, to make sure sync_filesystem() will not be skipped. Signed-off-by: -

https://bugzilla.kernel.org/show_bug.cgi?id=200951 These is a NULL pointer dereference issue reported in bugzilla: Hi, in the setup there is a SATA SSD connected to a SATA-to-USB bridge. The disc is "Samsung SSD 850 PRO 256G" which supports TRIM. There are four partitions: sda1: FAT /boot sda2: F2FS / sda3: F2FS /home sda4: F2FS The bridge is ASMT1153e which uses the "uas" driver. There is no TRIM pass-through, so, when mounting it reports: mounting with "discard" option, but the device does not support discard The USB host is USB3.0 and UASP capable. It is the one on RK3399. Given this everything works fine, except there is no TRIM support. In order to enable TRIM a new UDEV rule is added [1]: /etc/udev/rules.d/10-sata-bridge-trim.rules: ACTION=="add|change", ATTRS{idVendor}=="174c", ATTRS{idProduct}=="55aa", SUBSYSTEM=="scsi_disk", ATTR{provisioning_mode}="unmap" After reboot any F2FS write hangs forever and dmesg reports: Unable to handle kernel NULL pointer dereference Also tested on a x86_64 system: works fine even with TRIM enabled. same disc same bridge different usb host controller different cpu architecture not root filesystem Regards, Vicenç.

This patch is used to fix nds32 allmodconfig/allyesconfig build error because GCOV kernel embeds counters in the kernel for each line and a part of that embed in __exit text. So we need to keep the EXIT_TEXT and EXIT_DATA if CONFIG_GCOV_KERNEL=y. Link: https://lkml.org/lkml/2018/9/1/125Signed-off-by:

Remove the verbose license text from NILFS2 files and replace them with SPDX tags. This does not change the license of any of the code. Link: http://lkml.kernel.org/r/1535624528-5982-1-git-send-email-konishi.ryusuke@lab.ntt.co.jpSigned-off-by:
