In 'libxfs/xfs_trans_resv.c', the comment for transaction of removing a
directory entry writes:
/* libxfs/xfs_trans_resv.c begin */
/*
* For removing a directory entry we can modify:
* the parent directory inode: inode size
* the removed inode: inode size
...
/* libxfs/xfs_trans_resv.c end */
There has 2 inode size of space to be reserverd, but the actual code
for inode reservation space writes:
/* libxfs/xfs_trans_resv.c begin */
/*
* For removing a directory entry we can modify:
* the parent directory inode: inode size
* the removed inode: inode size
...
xfs_calc_remove_reservation(
struct xfs_mount *mp)
{
return XFS_DQUOT_LOGRES(mp) +
xfs_calc_iunlink_add_reservation(mp) +
max((xfs_calc_inode_res(mp, 1) +
...
/* libxfs/xfs_trans_resv.c end */
There only count for 1 inode size to be reserved in
'xfs_calc_inode_res(mp, 1)', rather than 2.
