If there is no specific configuration of the felix switch in the device

uprobe_write_opcode() must not cross page boundary; prepare_uprobe()
relies on arch_uprobe_analyze_insn() which should validate "vaddr" but
some architectures (csky, s390, and sparc) don't do this.

We find that xfs_inode_set_reclaim_tag() and xfs_reclaim_inode() are
concurrently executed at runtime in the following call contexts:
Thread1:
xfs_fs_put_super()
xfs_unmountfs()
xfs_rtunmount_inodes()
xfs_irele()
xfs_fs_destroy_inode()
xfs_inode_set_reclai

Hi folks,
The vfs-for-next branch of the xfs-linux repository at:
git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git
has just been updated.
After a very, very long process of discussing how sysadmins and app
programmers are supposed to tag files for DAX data access mode, we have

To get exact count of free and used objects slub have to scan list of
partial slabs. This may take at long time. Scanning holds spinlock and
blocks allocations which move partial slabs to per-cpu lists and back.
Example found in the wild:
# cat /sys/kernel/slab/dentry/partial
