Bug#884938: XFS: possible memory allocation deadlock in kmem_alloc
Package: src:linux
Version: 3.16.51-3
Severity: normal
Writing a large number of files to an XFS system with a larger
directory block size causes slow performance and kernel log errors re:
memory allocation deadlocks.
On the surface, looks very similar to this ubuntu issue:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1382333
This has been reproducible on 2/2 systems I've tried so far.
xfs_info output for the affected filesystem:
meta-data=/dev/sdf isize=2048 agcount=55, agsize=268435455 blks
= sectsz=512 attr=2, projid32bit=1
= crc=0 finobt=0
data = bsize=4096 blocks=14648409600, imaxpct=1
= sunit=0 swidth=0 blks
naming =version 2 bsize=65536 ascii-ci=0 ftype=0
log =internal bsize=4096 blocks=521728, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
To reproduce, make an XFS filesystem with a large directory block size:
# /sbin/mkfs.xfs -n size=64k /dev/sdXX
Then mount the new filesystem and create a large number of small files quickly:
$ seq -w 0 10000000 | xargs -P8 -n 256 touch
