https://maloo.whamcloud.com/test_sets/d32b51c6-8b24-11e2-965f-52540035b04c This time it was conf-sanity 58b. |

This is due to recent request buffer shrinking effort, which makes SETXATTR unable to accept requests with maximum extend attribute size (64 KB). 49386 is exactly current intended max size for SETXATTR, while 65928 is how much needed. |

Looks like this is mostly hitting on review-zfs because ZFS has "large xattr" enabled by default, but that isn't currently enabled for ldiskfs by default, but the bug would be applicable to both. We should really squash the last remaining ZFS test failures and enable ZFS testing for real, so we don't keep introducing failures like this that are not caught "because ZFS tests always fail"... |
