vfs: switch ->show_options() to struct dentry *

switch ->create() to umode_t

2012-01-04T03:54:53+00:00

vfs_create() ignores everything outside of 16bit subset of its
mode argument; switching it to umode_t is obviously equivalent
and it's the only caller of the method

switch vfs_mkdir() and ->mkdir() to umode_t

2012-01-04T03:54:53+00:00

vfs_mkdir() gets int, but immediately drops everything that might not
fit into umode_t and that's the only caller of ->mkdir()...

vfs: fix the stupidity with i_dentry in inode destructors

2012-01-04T03:52:40+00:00

Seeing that just about every destructor got that INIT_LIST_HEAD() copied into
it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once();
the cost of taking it into inode_init_always() will be negligible for pipes
and sockets and negative for everything else.  Not to mention the removal of
boilerplate code from ->destroy_inode() instances...

vfs: mnt_drop_write_file()

2012-01-04T03:52:40+00:00

new helper (wrapper around mnt_drop_write()) to be used in pair with
mnt_want_write_file().

Signed-off-by: Al Viro

switch a bunch of places to mnt_want_write_file()

2012-01-04T03:52:35+00:00

it's both faster (in case when file has been opened for write) and cleaner.

freezer: unexport refrigerator() and update try_to_freeze() slightly

2011-11-21T20:32:22+00:00

There is no reason to export two functions for entering the
refrigerator.  Calling refrigerator() instead of try_to_freeze()
doesn't save anything noticeable or removes any race condition.

* Rename refrigerator() to __refrigerator() and make it return bool
  indicating whether it scheduled out for freezing.

* Update try_to_freeze() to return bool and relay the return value of
  __refrigerator() if freezing().

* Convert all refrigerator() users to try_to_freeze().

* Update documentation accordingly.

* While at it, add might_sleep() to try_to_freeze().
