JFS: Remove redundant xattr permission checking

2006-11-02T16:50:40+00:00

The vfs handles most permissions for setting and retrieving xattrs.
This patch removes a redundant and wrong check so that it won't override
the correct behavior which is being fixed in the vfs.

JFS: pageno needs to be long

2006-10-13T17:42:36+00:00

diRead and diWrite are representing the page number as an unsigned int.
This causes file system corruption on volumes larger than 16TB.

[PATCH] JFS: return correct error when i-node allocation failed

2006-10-02T14:51:01+00:00

I have seen confusing behavior on JFS when I injected many intentional
slab allocation errors. The cp command failed with no disk space error
with enough disk space.

This patch makes:

- change the return value in case slab allocation failures happen
  from -ENOSPC to -ENOMEM

- ialloc() return error code so that the caller can know the reason
  of failures

[PATCH] r/o bind mounts: monitor zeroing of i_nlink

2006-10-01T07:39:30+00:00

Some filesystems, instead of simply decrementing i_nlink, simply zero it
during an unlink operation.  We need to catch these in addition to the
decrement operations.

[PATCH] r/o bind mount prepwork: inc_nlink() helper

2006-10-01T07:39:30+00:00

This is mostly included for parity with dec_nlink(), where we will have some
more hooks.  This one should stay pretty darn straightforward for now.

[PATCH] r/o bind mounts: unlink: monitor i_nlink

2006-10-01T07:39:30+00:00

When a filesystem decrements i_nlink to zero, it means that a write must be
performed in order to drop the inode from the filesystem.

We're shortly going to have keep filesystems from being remounted r/o between
the time that this i_nlink decrement and that write occurs.

So, add a little helper function to do the decrements.  We'll tie into it in a
bit to note when i_nlink hits zero.

[PATCH] Streamline generic_file_* interfaces and filemap cleanups

2006-10-01T07:39:28+00:00

This patch cleans up generic_file_*_read/write() interfaces.  Christoph
Hellwig gave me the idea for this clean ups.

In a nutshell, all filesystems should set .aio_read/.aio_write methods and use
do_sync_read/ do_sync_write() as their .read/.write methods.  This allows us
to cleanup all variants of generic_file_* routines.

Final available interfaces:

generic_file_aio_read() - read handler
generic_file_aio_write() - write handler
generic_file_aio_write_nolock() - no lock write handler

__generic_file_aio_write_nolock() - internal worker routine
