XFS issue in Linux 2.6.17



XFS issue with directory corruption in Linux 2.6.17

In the Linux kernel 2.6.17 release a subtle bug was accidentally introduced into the XFS directory code by some "sparse" endian annotations. This bug was sufficiently uncommon (it only affects a certain type of format change, in Node or B-Tree format directories, and only in certain situations) that it was not detected during our regular regression testing, but it has been observed in the wild by a number of people now.

Update: the fix is included in 2.6.17.7 and later kernels.
