2016-01-22wrappers for ->i_mutex accessAl Viro1-2/+2
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 <viro@zeniv.linux.org.uk>

2014-03-04efivarfs: 'efivarfs_file_write' function reorganizationGeyslan G. Bem1-9/+4
This reorganization removes useless 'bytes' prior assignment and uses 'memdup_user' instead 'kmalloc' + 'copy_from_user'. Signed-off-by: Geyslan G. Bem <geyslan@gmail.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
2013-05-13efivarfs: Never return ENOENT from firmware againLingzhu Xiang1-2/+12
Previously in 1fa7e69 efi_status_to_err() translated firmware status EFI_NOT_FOUND to -EIO instead of -ENOENT for efivarfs operations to avoid confusion. After refactoring in e14ab23, it is also used in other places where the translation may be unnecessary. So move the translation to efivarfs specific code. Also return EOF for reading zero-length files, which is what users would expect.

2013-04-17efivarfs: Move to fs/efivarfsMatt Fleming1-0/+111
Now that efivarfs uses the efivar API, move it out of efivars.c and into fs/efivarfs where it belongs. This move will eventually allow us to enable the efivarfs code without having to also enable CONFIG_EFI_VARS built, and vice versa. Furthermore, things like, mount -t efivarfs none /sys/firmware/efi/efivars will now work if efivarfs is built as a module without requiring the use of MODULE_ALIAS(), which would have been necessary when the efivarfs code was part of efivars.c.
