From: Raghavendra D Prabhu <rprabhu@xxxxxxxxxxx>
Currently, when there are no free inodes left / free space to allocate them (usually
without inode64), there is no indication anywhere of this case, making it harder
to diagnose this case.
Hence, this series prints the causes/reasons to kernel log in a ratelimited
manner, when such a situation arises.
Regarding why it is printed at callee location instead at caller, it gives
greater granularity in expressing the precise reason and give more details, and
also some along the path are not ENOSPC (such in xfs_ialloc where ialloc_context is not NULL but
ino is) along with the fact that it (xfs_ialloc) is called at multiple sites, so to avoid duplication.
Version 1: Initial series.
Version 2: Added ratelimited printing to xfs_message and used that.
Version 3: Kept the logic intact in few places, fixed the column requirement.
Raghavendra D Prabhu (3):
xfs: Add ratelimited printk for different alert levels
xfs: Print error when xfs_ialloc_ag_select fails to find continuous
free space.
xfs: Print error when unable to allocate inodes or out of free
inodes.
