2012-04-02udf: Fix deadlock in udf_release_file()Jan Kara
commit a0391a3ae91d301c0e59368531a4de5f0b122bcf upstream. udf_release_file() can be called from munmap() path with mmap_sem held. Thus we cannot take i_mutex there because that ranks above mmap_sem. Luckily, i_mutex is not needed in udf_release_file() anymore since protection by i_data_sem is enough to protect from races with write and truncate.

2012-02-13udf: Mark LVID buffer as uptodate before marking it dirtyJan Kara
commit 853a0c25baf96b028de1654bea1e0c8857eadf3d upstream. When we hit EIO while writing LVID, the buffer uptodate bit is cleared. This then results in an anoying warning from mark_buffer_dirty() when we write the buffer again. So just set uptodate flag unconditionally.

2012-01-12udf: Fix deadlock when converting file from in-ICB one to normal oneJan Kara
commit d2eb8c359309ec45d6bf5b147303ab8e13be86ea upstream. During BKL removal in 2.6.38, conversion of files from in-ICB format to normal format got broken. We call ->writepage with i_data_sem held but udf_get_block() also acquires i_data_sem thus creating A-A deadlock. We fix the problem by dropping i_data_sem before calling ->writepage() which is safe since i_mutex still protects us against any changes in the file. Also fix pagelock - i_data_sem lock inversion in udf_expand_file_adinicb() by dropping i_data_sem before calling find_or_create_page().

2011-01-07fs: icache RCU free inodesNick Piggin
RCU free the struct inode. This will allow: - Subsequent store-free path walking patch. The inode must be consulted for permissions when walking, so an RCU inode reference is a must. - sb_inode_list_lock to be moved inside i_lock because sb list walkers who want to take i_lock no longer need to take sb_inode_list_lock to walk the list in the first place. This will simplify and optimize locking. - Could remove some nested trylock loops in dcache code - Could potentially simplify things a bit in VM land. Do not need to take the page lock to follow page->mapping. The downsides of this is the performance cost of using RCU. In a simple creat/unlink microbenchmark, performance drops by about 10% due to inability to reuse cache-hot slab objects. As iterations increase and RCU freeing starts kicking over, this increases to about 20%. In cases where inode lifetimes are longer (ie. many inodes may be allocated during the average life span of a single inode), a lot of this cache reuse is not applicable, so the regression caused by this patch is smaller. The cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU, however this adds some complexity to list walking and store-free path walking, so I prefer to implement this at a later date, if it is shown to be a win in real situations. I haven't found a regression in any non-micro benchmark so I doubt it will be a problem. Signed-off-by: Nick Piggin <npiggin@kernel.dk>
2011-01-06UDF: Close small mem leak in udf_find_entry()Jesper Juhl
Hi, There's a small memory leak in fs/udf/namei.c::udf_find_entry(). We dynamically allocate memory for 'fname' with kmalloc() and in most situations we free it before we leave the function, but there is one situation where we do not (but should). This patch closes the leak by jumping to the 'out_ok' label which does the correct cleanup rather than doing half the cleanup and returning directly.

2011-01-06udf: Fix directory corruption after extent mergingJan Kara
If udf_bread() called from udf_add_entry() managed to merge created extent to an already existing one (or if previous extents could be merged), the code truncating the last extent to proper size would just overwrite the freshly allocated extent with an extent that used to be in that place. This obviously results in a directory corruption. Fix the problem by properly reloading the last extent. Signed-off-by: Jan Kara <jack@suse.cz>
