New helper - current_umask()

2009-04-01T03:00:26+00:00

current->fs->umask is what most of fs_struct users are doing.
Put that into a helper function.

proc 2/2: remove struct proc_dir_entry::owner

2009-03-30T21:14:44+00:00

Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.

We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.

But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.

->read_proc/->write_proc were just fixed to not require ->owner for
protection.

rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.

Removing ->owner will also make PDE smaller.

So, let's nuke it.

Kudos to Jeff Layton for reminding about this, let's say, oversight.

jfs: needs crc32_le

2009-02-02T19:43:28+00:00

JFS needs crc32_le(), so select its library config symbol:

fs/built-in.o: In function `jfs_statfs':
super.c:(.text+0x7c8c0): undefined reference to `crc32_le'
super.c:(.text+0x7c8d5): undefined reference to `crc32_le'

jfs: Fix error handling in metapage_writepage()

2009-01-30T20:09:06+00:00

Improved error handling so that last_write_complete(), and thus
end_page_writeback(), gets called only once.

jfs: return f_fsid for statfs(2)

2009-01-27T16:56:14+00:00

This patch makes jfs return f_fsid info for statfs(2). By Andreas'
suggestion, this patch populates a persistent f_fsid between boots/mounts
with help of on-disk uuid record.
