Subject: GFS2: return -E2BIG if hit the maximum limits of ACLs
X-Git-Tag: v3.15-rc1~97^2~14
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f2113eb8a4ede4016199492f3e10f5a165b04fcd;p=karo-tx-linux.git

GFS2: return -E2BIG if hit the maximum limits of ACLs

Return -E2BIG rather than -EINVAL if hit the maximum size limits of
ACLs, as the former errno is consistent with VFS xattr syscalls.

This is pointed out by Dave Chinner in previous discussion thread:
