Unlinking objects in a directory with sticky bit set

[Matthew Dillon]

:Quoting from sticky(8):
:  ... A file in a sticky directory may only be removed or renamed
:  by a user if the user has write permission for the directory and the user
:  is the owner of the file, the owner of the directory, or the super-user.
:
:So rename(2) in a directory with sticky bit set should also be taken care of.
:Currently there are three commits to be cherry-picked to 2.2 branch:
:  918101d3be679a76c85ea8f47b94e05f8eb11ee5
:  ee89633d5330733056052c06919a5dd4c01347bc
:  dae8d54f0708cf191cbb06ef6aa43cd570ceea90
:
:The filesystems affected by ee89633d are: ext2fs, hpfs, msdosfs, ntfs,
:nwfs, smbfs, udf, ufs, and HAMMER, but I only tested ufs and HAMMER.

    Is rename(2) working properly?  I wasn't quite sure from your posting.
    It does seem to work properly in my quick test.

:And a very silly nit-pick would be that with these commits the return
:code is changed from EPERM to EACCES.  I can't think of a situation
:when that could be a problem, though.
:

    I don't mind synchronizing the error code with linux, if someone wants
    to figure out what linux returns in these situations.
