powerpc/ps3: make system bus's remove and shutdown callbacks return void

2020-12-03T14:01:22+00:00

The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. For the shutdown callback it's ps3_system_bus_shutdown() which ignores the return value. To simplify the quest to make struct device_driver::remove return void, let struct ps3_system_bus_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

wrappers for ->i_mutex access

2016-01-22T23:04:28+00:00

parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested}, inode_foo(inode) being mutex_foo(&inode->i_mutex). Please, use those for access to ->i_mutex; over the coming cycle ->i_mutex will become rwsem, with ->lookup() done with it held only shared. Signed-off-by: Al Viro

drivers/char: Add module.h to those who were using it implicitly

2011-10-31T23:31:40+00:00

A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in char are actually calling out for explicitly in advance. Signed-off-by: Paul Gortmaker

fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers

2011-07-21T00:47:59+00:00

Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

Fix up a few ->llseek() implementations that won't deal with SEEK_HOLE/SEEK_DATA properly. Make them future proof so that if we ever add new options they will return -EINVAL. Thanks, Signed-off-by: Josef Bacik Signed-off-by: Al Viro
