udf: Fix deadlock in udf_release_file()

2012-04-02T16:53:04+00:00

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.

udf: Mark LVID buffer as uptodate before marking it dirty

2012-02-13T19:16:56+00:00

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.

udf: Fix deadlock when converting file from in-ICB one to normal one

2012-01-12T19:29:37+00:00

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().

treewide: use printf not attribute__((format(printf,...)))

2011-11-01T00:30:54+00:00

Standardize the style for compiler based printf format verification.
Standardized the location of __printf too.

Done via script and a little typing.

$ grep -rPl --include=*.[ch] -w "__attribute__" * | \
  grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \
  xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*\(\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*\)\s*\)\s*\)/__printf($1, $2)/g ; print; }'

udf: Skip mirror metadata FE loading when metadata FE is ok

2011-10-31T22:49:30+00:00

It is not necessary to load mirror metadata FE when metadata FE is OK.  So try
to read it only the first time udf_get_pblock_meta25() fails to map the block
from metadata FE.
