| * block: remove per-queue pluggingJens Axboe2011-03-10
| | | | | | | | | | | | | | | | Code has been converted over to the new explicit on-stack plugging, and delay users have been converted to use the new API for that. So lets kill off the old plugging along with aops->sync_page(). Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
* | adfs: add hexadecimal filetype suffix optionStuart Swales2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ADFS (FileCore) storage complies with the RISC OS filetype specification (12 bits of file type information is stored in the file load address, rather than using a file extension). The existing driver largely ignores this information and does not present it to the end user. It is desirable that stored filetypes be made visible to the end user to facilitate a precise copy of data and metadata from a hard disc (or image thereof) into a RISC OS emulator (such as RPCEmu) or to a network share which can be accessed by real Acorn systems. This patch implements a per-mount filetype suffix option (use -o ftsuffix=1) to present any filetype as a ,xyz hexadecimal suffix on each file. This type suffix is compatible with that used by RISC OS systems that access network servers using NFS client software and by RPCemu's host filing system.

* | adfs: improve timestamp precisionStuart Swales2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ADFS (FileCore) storage complies with the RISC OS timestamp specification (40-bit centiseconds since 01 Jan 1900 00:00:00). It is desirable that stored timestamp precision be maintained to facilitate a precise copy of data and metadata from a hard disc (or image thereof) into a RISC OS emulator (such as RPCEmu). This patch implements a full-precision conversion from ADFS to Unix timestamp as the existing driver, for ease of calculation with old 32-bit compilers, uses the common trick of shifting the 40-bits representing centiseconds around into 32-bits representing seconds thereby losing precision.

* | adfs: remove the big kernel lockArnd Bergmann2011-03-01
|/ | | | | | | | | | | | | According to Russell King, adfs was written to not require the big kernel lock, and all inode updates are done under adfs_dir_lock. All other metadata in adfs is read-only and does not require locking. The use of the BKL is the result of various pushdowns from the VFS operations.

* check ATTR_SIZE contraints in inode_change_okChristoph Hellwig2010-08-09
| | | | | | | | | | | | | | | | | | | | | Make sure we check the truncate constraints early on in ->setattr by adding those checks to inode_change_ok. Also clean up and document inode_change_ok to make this obvious. As a fallout we don't have to call inode_newsize_ok from simple_setsize and simplify it down to a truncate_setsize which doesn't return an error. This simplifies a lot of setattr implementations and means we use truncate_setsize almost everywhere. Get rid of fat_setsize now that it's trivial and mark ext2_setsize static to make the calling convention obvious. Keep the inode_newsize_ok in vmtruncate for now as all callers need an audit for its removal anyway. Note: setattr code in ecryptfs doesn't call inode_change_ok at all and needs a deeper audit, but that is left for later.

* get rid of cont_write_begin_newtruncChristoph Hellwig2010-08-09
| | | | | | | | | Move the call to vmtruncate to get rid of accessive blocks to the callers in preparation of the new truncate sequence and rename the non-truncating version to cont_write_begin. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* kill spurious reference to vmtruncatenpiggin@suse.de2010-05-27
| | | | | | | | | | Lots of filesystems calls vmtruncate despite not implementing the old ->truncate method.

* pass writeback_control to ->write_inodeChristoph Hellwig2010-03-05
| | | | | | | | | | This gives the filesystem more information about the writeback that is happening. Trond requested this for the NFS unstable write handling, and other filesystems might benefit from this too by beeing able to distinguish between the different callers in more detail.

* [PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o2006-09-27
| | | | | | | | | | | | | | | | This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
