missing unlock in jfs_quota_write()
We should unlock &inode->i_mutex on the error path. This bug was in ext2_quota_write(). I sent a patch to them today as well. Found by smatch (http://repo.or.cz/w/smatch.git). Compile tested. regards, dan carpenter Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com>
